I have a CSV file with data like:
ID,Name,Role,Project
1,James,Owner,TST
2,Ed,Assistant,TST
3,Jack,Manager,TST
and want to create people whose relationships to the project are therein specified. I attempted to do it like this:
load csv from 'file:/../x.csv' as line
match (p:Project {code: line[3]})
create (n:Individual {name: line[1]})-[r:line[2]]->(p);
but it barfs with:
Invalid input '[': expected an identifier character, whitespace, '|', a length specification, a property map or ']' (line 1, column 159 (offset: 158))
as it can't seem to dereference line in the relationship creation. if I hard-code that it works:
load csv from 'file:/../x.csv' as line
match (p:Project {code: line[3]})
create (n:Individual {name: line[1]})-[r:WORKSFOR]->(p);
so how do I make the reference?
Right now you can't as this is structural information.
Either use neo4j-import tool for that.
Or specify it manually as you did, or use this workaround:
load csv with headers from 'file:/../x.csv' as line
match (p:Project {code: line.Project})
create (n:Individual {name: lineName})
foreach (x in case line.Role when "Owner" then [1] else [] end |
create (n)-[r:Owner]->(p)
)
foreach (x in case line.Role when "Assistant" then [1] else [] end |
create (n)-[Assistant]->(p)
)
foreach (x in case line.Role when "Manager" then [1] else [] end |
create (n)-[r:Manager]->(p)
)
